The verdict, explained

At 21.25x15.25x10", the Samsonite Freeform Hardside Expandable Spinner fits inside Southwest Airlines's 24x16x10" carry-on allowance, right at the limit. It should slide into the overhead bin without trouble at the gate sizer. On Southwest Airlines: Generous 24x16x10 carry-on plus two free checked bags. It is too large for Southwest Airlines's under-seat personal-item space, so it has to go overhead or be checked.

Airlines measure at the widest external point — wheels, handles, and bulging pockets all count. Pull soft-bag compression straps fully tight before you size it.
